Perform Post-Upgrade Steps

Do the following steps after you upgrade Data Aggregator:

• If you applied the Java Cryptography Extension (JCE) for Java 6, which enhances the security policy strength, consider that Data Aggregator uses Java 7. If you require this enhanced security, reapply the latest JCE after upgrading.

  Note: For the Java 7 version of the JCE, visit the Oracle site.

• Upgrading Data Aggregator backs up the /opt/IMDataAggregator/apache-karaf-X.X.X directory to the /opt/IMDataAggregator/backup/apache-karaf directory. Customizations that are located in the /opt/IMDataAggregator/apache-karaf-X.X.X/etc/ directory, such as default logging levels or other configurations are backed up, but are not restored to the installation directory automatically. To avoid losing these customizations, restore the customizations manually after you have successfully upgraded.

  For example, suppose that you have a custom configuration where you update the local-jms-broker.xml in the /opt/IMDataAggregator/apache-karaf-X.X.X/deploy directory. After the upgrade, the local-jms-broker.xml inside the /opt/IMDataAggregator/apache-karaf-X.X.X/deploy directory comes from the latest installer. The customized jms broker file is backed up in the /opt/IMDataAggregator/backup/apache-karaf directory. To preserve the custom modification, find the backed up file and then reapply the customization to the installed directory.

• Upgrading Data Collector backs up the /opt/IMDataCollector/apache-karaf-X.X.X directory to the /opt/IMDataCollector/backup/apache-karaf directory. Customizations that are located in the /opt/IMDataCollector/apache-karaf-X.X.X/etc/ directory, such as default logging levels or other configurations are backed up, but are not restored to the installation directory automatically. To avoid losing these customizations, restore the customizations manually after you successfully upgraded.
• Prioritize vendor certifications. After you upgrade Data Aggregator, new vendor certifications are placed at the bottom of the Vendor Certification Priorities list for the corresponding metric family. To take advantage of the new vendor certifications, manually change the vendor certification priorities. For example, F5 CPU vendor certifications are modeled as normal CPUs but do not get discovered because F5 also supports Host Resources. After an upgrade, the Host Resources CPU priority entry will be higher than the F5 entries appended to the end of the priority list. To discover F5 CPU devices and components, update the vendor certification priority for the CPU metric family.

  Note: For information about prioritizing vendor certifications, see the Data Aggregator Self-Certification Guide.

• Reapply memory settings on CA Performance Center. For large-scale deployments, we recommend customizing your default maximum memory usage settings. These customized settings are not reapplied automatically during an upgrade. To take advantage of your custom memory settings, reapply them manually after upgrading.

  Do the following steps:

  1. Open Installation Directory/PerformanceCenter/SERVICE/conf/wrapper.conf.old.

     Note: SERVICE refers to the following subdirectories for the services:

     • PC (Performance Center Console Service)
     • DM (Performance Center Device Manager Service)
     • EM (Performance Center Event Manager Service)

     Example: /opt/CA/PerformanceCenter/PC/conf/wrapper.conf.old

  2. Locate the “wrapper.java.maxmemory” property, and note the specified value.
  3. Open Installation Directory/PerformanceCenter/SERVICE/conf/wrapper.conf.

     Example: /opt/CA/PerformanceCenter/PC/conf/wrapper.conf

  4. Locate the “wrapper.java.maxmemory” property, and set it to the value from step 2. Save.

     Stop and restart each daemon by entering the following commands:

     service service name stop
     

     service service name start
     

  5. Repeat steps 1–5 for each of the services.

     Your custom memory settings are reapplied.
